When the plunger is pulled into the coil all the way, the pinion fully engages the ring gear. When the ring gear is fully engaged, engine cranking begins. When the engine starts the hold-in coil will cut out and the plunger will move out, retracting the pinion and opening the starter switch.

The fixture should support the board and prevent distortion as the board goes through the printing, component placement, and reflow processes. Its construction should ensure adequate protection for the bottom side components during the double-sided reflow process.

The remaining part joins the separate boards and is then cut with a machine during the depaneling. This helps to reduce the stress on the PCB. One challenge with the V-groove method is that it is restrictive and cannot be used with PCBs that have overhanging components over the edges.

They have to be connected to the arduino through a motor shield or custom built circuit. They are typically the most expensive. Stepper motors can have 4, 5, 6, or 8 wires. To use them with the arduino, understanding the internal wiring is absolutely necessary. The best way to learn the internal wiring is to assume no manual exists, and "discover" the internal wiring.

Today servomechanisms are used in automatic machine tools, satellite-tracking antennas, remote control airplanes, automatic navigation systems on boats and planes, and antiaircraft-gun control systems. Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometre positioning accuracy. In industrial machines, servos are used to perform complex motion, in many applications.

STARTER MOTOR — This is a powerful electric motor that engages the cars flywheel in order to spin the crankshaft. As in all electric motors, the starter is composed of windings of wire that form loops, ending at the commutator segments "remember these from the generator". The armature coils are mounted on the motors central shaftsupported with bearings and the field coils are formed into four or more "shoes", placed inside the steel frame of the starter.

Some can carry more than one board hence allowing the processing of multiple PCBs simultaneously. Other designs have adjustments to support both the primary and secondary side processes.

Making repairs to the loom Use a circuit tester to check if single wires are damaged. The wiring loom itself seldom goes wrong, but after other repairs have been made, a cable may be trapped and its insulation cut through, causing a short circuit.
